How to Use
This tool predicts a child's potential adult height based on genetic factors. It uses scientifically-backed formulas that consider parental heights and gender.
Step-by-Step Instructions:
- Select Method: Choose between "Parent heights method" or "Child foot length method"
- Choose Gender: Select whether the child is male or female
- Enter Heights: Input both father's and mother's heights in centimeters
- Calculate: Click the "Calculate" button to get the prediction
Height Prediction Formulas:
- For Boys: (Father's height + Mother's height) × 1.08 ÷ 2
- For Girls: (Father's height × 0.923 + Mother's height) ÷ 2
Examples:
- Boy Example: Father 175cm + Mother 165cm = (175+165)×1.08÷2 = 183.6cm predicted height
- Girl Example: Father 180cm + Mother 160cm = (180×0.923+160)÷2 = 163.1cm predicted height
